I see. But bare in mind that today's gamers play at 1920/1080 as a normal gaming resolution. That's why i am targeting this resolution as the main one. I am also using bigger images so I can test the hit in the system.
I have external monitor that can handle that,unfortunatly when I connected it to HDMI ,it failed to work

as long as you keep your game as window it can be dragged to secondary monitor,once you make it fullscreen you cant
would be cool if you ported it to Xbox One,ps4 that is capable o running at 1920x1080 HDtv resolution,its x86/x64 hardware under the hood
I have one old XP box, thats capable of 1920x1080,but I don't know if its capable of running your game,because I dont know if you use the latest SIMD opcodes?
